2 Claims.

This invention relates in general to a collapsible display comprising two or more pieces of material which are movable apart and connected at their proximate edges by an extensible and collapsible strip or sheet having related slots or slits therein mitting a considerable separation of the parts,

depending upon the width of the lattice-work and at the same time permitting a return or collapse of the parts without lateral displacement of the parts by such movement.

A further object of the invention is yto provide .a display in which one part is offset from another by means of lattice-work connected thereto with means for releasably holding the parts and the lattice-work in such extended position.

A still further object of the invention is in the provision of a display having parts connected and movable apart to a limited extent by means of a connected lattice-work, and in the provision of distending and limiting means for confining the extended and collapsing movement within the proper limits. J

Other objects of the invention will appear in the specification and will be apparent from the accompanying drawings, in which,

Fig. 1 is a plan view of a circular display constructed in accordance with this invention;

Fig. 2 is a sectional distended view of the display taken on the line 3--3 of Fig. 1;

Fig. 2a is a sectional View of the parts shown in Fig. 2 in at folded position;

Fig. 3 is a sectional distended view of the display as taken on the lines 4 4 of Fig. 1;

Fig. 4 is a side elevation of a portion of the display illustrating the extension of the latticework;

Fig. 5 is a detail perspective illustrating the display extending and limiting means;

Fig. 6 is a section taken on the line 5 6 of Fig. 5; and

Fig. 7 shows a blank as cut to form one of the parts of the display.

This invention relates to a novel display construction by which two parts ordinarilymovable apart for display and collapsed together for storing and shipping are connected by a contrasting piece of material such as a strikingly colored lattice member which will expandand collapse to a limited extent without tearing or disruption, and will maintain the parts in corresponding position without relative lateral or rotative movement. Although lattice-work made of paper or other `similar' material is known and used, the present invention relates particularly to its use in a display and to the means for controlling and limiting the extending and collapsing thereof.

Referring now moreparticularly to the drawings, the invention is described in connection with a display having a circular center part I d, an outer circular rim H, and an interposed lattice ring I2. While this construction is merely illustrative of the type of displays or constructions which may be included in the present invention,

the particular form shown is also desirable asa display, and may have parts of other shapes and forms rather than the circular pieces as shown.

The lattice ring or member comprises .a sheet such as paper, cardboard or other flexible material, having solid or imperforate edges I3 and I4 with an intermediate lattice portion formed by parallel slits l5 cut through the material and the cuts arranged in parallel lines, the cuts of one line being staggered or offset with the cuts of the adjacent lines so that a connected network is formed which is capable or expansion and contraction to a limited extent without tearing the material and by attaching the imperforate edges, an attractive network is provided for connecting two adjacent parts without lateral or rotative movement of one part with respect to the other. One imperforate edge I3 is attached to the under-side of the margin of the part I and the other imperforate edge I4 is attached to the rear Side 0f the Outer Dart Il, or is included as shown, between the part I0 and a back plate IB which constitutes a support for the entire display. The edges I3 and I4 are adhesively attached or connected to the parts in any other desired manner, the intermediate latticed construction preferably lying flat between the connected parts when they are in collapsed position, and extending angularly between the parts when they are extended. By making the slits l5 short and closely spaced in each row, staggered with respect to those in adjacent rows,'the surface of the inclined lattice work appears Substantially continuous when Viewed from the front, the small apertures formed by the slits being apparent from the side or edge of the display.

In order to control the extending movement of the lattice connection, the back plate I6 is cut and scored at the center behind the extensible display part i0, as clearly shown in Fig. 7, to provide extension props l1 and limiting members I8.

Each extension prop is substantially rectangular in outline, is hinged to the back plate by a partial severing line I9, the outer edge 2t engages the inner or rear side of the central display plate or part Il] to hold it outwardly and to distend the lattice-work a distance equal to the width of the prop.

As shown, the props I7 and limiting members I8 are alternated and are adjacent each other, each limiting member comprising connected hinged members 2| and 22 and an outer attaching member 23, all connected by partially cut lines 24, 25 and 26 which form the hinges. At the ends ofeachattach'i-ng member 23 are notches 21 adapted to be engaged by the outer extremities of the next adjacent extension props l' and this end extension of each of the attaching members being therefore cut out of the edges of the adjacent props forming recesses 28 inthe props which constitute finger-engaging portions Vfor raising or disengaging the props in collapsing the display.

Each attaching member 23 is, adhesively or otherwise permanently secured to the back or under side of the'central display part l!) and the hinging members 2| and 22 are together of a slightly greater Width than the Width of the extension props I'l so that when the props are in place, extending the lattice-Work toits greatest extent, the members 2I and 22 are not in alignment vbut preserve an angular position with respect to each other as shown more clearly in Fig. 3, andalso with respect to the prop i1, as shown in perspective in Fig. 2. Due to the resilience of the material and the hinging connection of these parts, this resilience permits the props to be yieldingly pushed into place against the stop notches 21 and `disengaged therefrom, Ylimiting thejseparation or opening movement Aof the lattice-Work and maintaining it resiliently'in its eX- tended'position.

While this lattice construction is shown in a circular display in Which the parts are separated an equal amount all around, a similar lattice may be used to connect any two parts for display purposes and greater or less separation may be provided by making the lattice-work of different Widths as desired. In any foldable or collapsible display it is desirable to limit the extending movement of the lattice-work, as it is easily torn if extended too far, and to provide a resilient prop for holding it in distended position which may be easily disengaged for collapsing the display.

I claim:

1.7I'n a lattice display, a central part, a supporting back extending outwardly beyond the central member, a flexible latticed sheet connected at its edges to the central part and out- Wardlytherefrom to the outer edge of the supporting back, the intermediate portion of the lattice sheet having slits to form anv open latticework when the central part is moved relative to the back, hinged tongues formed in the back member at the rear of the central part and covered thereby to engage and hold the central part 'in a projected position from the back, distending the lattice-Work, and a hinged tongue also formed of the material of the back and connected to the centralpart within the lattice-Work for limiting the projected movement of the central part and for `yieldingly holding it in place.

2. A structure in accordance with claim 1 in which the projecting tongues Vand the ,hinged limiting means are alternately disposed and are cut from the central portion of the back to form an attaching portion which is secured to the said .central part, this attaching portion being cut from the outer .edges of the distending tongues and formingnger-hold portions therein, and the said attachment portions having shoulders forming stops for engaging and limiting the extremities of the distending tongues in their distending movement, the tongues being .held in engagement Vtherewith by the resilience of the said limiting means.
